Which symbol represents electric current?

The symbol that represents electric current is "I." This notation originates from the French phrase "intensité de courant," which means "intensity of current." In electrical formulas and equations, current is measured in amperes (A), and the use of "I" helps standardize communication among engineers and technicians.

In contrast, other symbols represent different electrical concepts: "EMF" refers to electromotive force, which indicates the potential difference generated by a source; "kV" denotes kilovolts, a unit for measuring voltage; while "kVA" stands for kilovolt-amperes, which is a unit for apparent power. Understanding these distinctions is crucial for anyone working in electrical maintenance and engineering, as it ensures clarity in discussing various aspects of electrical systems.
